Plants turn yellow primarily because of issues that affect chlorophyll production and the plant's ability to photosynthesize properly. Some of the most common reasons include:
- Overwatering or underwatering: Too much water can suffocate roots and too little water can cause nutrient deficiency, both leading to yellow leaves.
- Poor drainage: Without proper drainage, soil remains soggy, damaging roots and causing yellowing.
- Inappropriate light: Too much direct sunlight can sunburn leaves, while too little light reduces photosynthesis.
- Nutrient deficiencies: Lack of essential nutrients like nitrogen, iron, magnesium, potassium, or sulfur can cause various yellowing patterns.
- Root problems like root rot or being rootbound interfere with nutrient and water uptake.
- Pests or fungal issues can also lead to yellow leaves.
- Soil pH imbalances can prevent nutrient absorption resulting in yellowing.
To fix yellow leaves, check watering habits, ensure good pot drainage, adjust light exposure according to the plant's needs, test and amend soil nutrients and pH, inspect for pests, and consider repotting if the plant is rootbound or has root rot. Each plant species has specific requirements, so referring to its care guide is helpful.
